2 Main SWFDP Goals Ø Improve Severe Weather Forecasting Ø Improve lead-time of Warnings Ø Improve interaction of NMHSs with users: media, disaster management, civil protection authorities Ø Identify areas for improvement and requirements for the Basic Systems Ø Improve the skill of products from WMO operational centres through feedback Ø Capacity building

3 SWFDP Cascading Forecasting Process Global NWP centres to provide available NWP and EPS products, including in the form of probabili<es Regional centre interprets informa<on from global centres, Prepare guidance forecasts for NMHSs, run LAM to refine products NMHSs reassess info and issue country forecasts and warnings to Disaster Management Offices, media and public etc. if needed 3

4 SWFDP Africa South Africa -16 Countries : Angola, WMO Botswana, Democratic Republic of the Congo, Malawi, Mauritius, Madagascar, Mozambique, Namibia, Lesotho, Seychelles, South Africa, Swaziland, Tanzania, Zambia, Zimbabwe, Comoros (Since 2006) Eastern Africa - 7 Countries: Burundi, Ethiopia, Kenya, Rwanda, South Sudan, Tanzania and Uganda West Africa: In Development

5 Issues around accessing and sharing information Weather business creates huge amount of data (Satellites, Radars, Surface & upper air observations etc). Accessing these data facilitates the development of accurate weather information and warnings High quality Numerical Weather Information is shared through internet but in most countries the availability or adequacy of Internet is the sore point The dissemination of warnings through internet is also hampered by the lack of Internet connection Where Fiber is available, the cost for accessing adequate Internet connection is prohibitive for many National Meteorological Services test footer 5

7 Africa historically relies extensively on V-SAT links in many parts ASECNA centres High bandwidth central service Senegal supporting: VSAT-64kps / TCP/IP to most centres Other NMHS typically using Fixed line or VSAT less than 64kps for dedicated networks VSAT 256kps lines for internet access Larger centres have fixed links through coastal fibre network (Eg Pretoria) High reliance on Sat Broadcast (EUMETSAT/Puma/etc) High reliance on Satellite Data Collection Systems (EUMETSAT) WMO Observation and Information System Department 7

10 Fibre is being rolled out in Africa Source: For country details - see wiki/ List_of_terrestrial_fibre _optic_cable_projects_i n_africa Varies from single to multiple in suppliers in each country Wouldn t it be nice to get Telco's to support NMHS needs WMO Observation and Information System Department

11 Regional WIGOS and WIS implementation Acknowledged that supplies and infrastructure were problematic for observation availability, but Identified that communications is a larger factor in missing observations Consistent with the Southern African Development Community - Meteorological theme group SADC master plan (2012) ( Regional_Infrastructure_Development_Master_Plan_Meteorology_ Sector_Plan.pdf) WMO Observation and Information System Department

12 SADC - Meteorology sector Vision 2027 The telecommunication infrastructure available to the NMSs does not support adequate transfer of data inside or outside the countries. Many do not have dependable access to the internet to consistently reach out to users for feedback on their products. WMO Observation and Information System Department
